This is an interventional multicenter prospective noninferiority non-randomized double-blind controlled before and after study.
The aim of this study is to demonstrate that standard precautions alone are not inferior to contact precautions by comparing the incidence density of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae acquired in geriatric units before and after discontinuing contact precautions.
Adult patient (> 65 years old)
Patient hospitalized in geriatrics during the study period
Free and informed consent obtained from the patient (or his trusted person or legal representative) within 48 hours of its admission at the geriatric unit
Patient affiliated to a social security scheme
Patient requiring contact precaution for an indication other than ESBL during the patient stay (COVID-19, classical PCC excluding EBLSE, Clostridium difficile PCC, scabies PCC and BHRe PCC)
Patient's stay period less than 4 days
